In order to practice at home, Tadeo purchased a basketball and a volleyball that cost a total of $67, not including tax. If the price of the basketball b is $4 more than twice the cost of the volleyball v. Which system of linear equations could be used to determine the price of each ball?

A. b + v = 67;  b = 2v ­- 4

B. b + v = 67;  b = 2v + 4

C. b + v = 4;  b = 2v ­- 67

D. b + v = 4;  b = 2v + 67
